This is the Slayer Exciter being run on indoor solar light only—no batteries. A small solar panel is capturing indirect solar energy through a window. The oscillator is shown not only illuminating leds but also transmitting a radio signal to a small radio nearby. An AV plug LED indicator is shown lighting up when put in a small glass of water.

A Chinese solar energy company received incentives to build a manufacturing plant in Austin.

So i wondering how large (acres, meters, miles, yards, sq ft) a solar energy plant has to be in order to supply enough energy to a small city and a little extra to transport to another city? And how much should one charge ($) for this clean renewable energy?
I am trying to make it in Egypt and it is very sunny there. SO would about 14,000 sq ft be enough to power a small city in egypt?

The metal grill shown here are at my disposal and I was wondering if I can use them to make solar panels at home for home use. I have 2 of these but there are like 1×2ft.

I would really like some step by step help on this one.
Thanks.
I need electricity not a system that heats water.
